Hello im Silverand i am in the traditon family, silver is used to make spoons, forks siver jewley and etc. My symbold is Ag and Atomic number is 47.why hello silver i am Potassium and i am found naturally in many different soils and iam one of the main essentials applied in fertilizers. iam also used to make batteries and liquid soap. myAtomic number is 19 and i have an amazing family named Alkail metal. oh why hello Silver and Potassium i amMercury and i am used in thermometers and baraometers. i also am a vapor used in street's and security lights. My atomic number is 80.
Very specfic properties , but different from the elements in it
Most use chemical reactions tp seperate a compound
Mixture
2 or more compounds that are not chemicly combinded
Properties vary depending on concentration
Physical Changes can be used to seperate changes
I learned that the substance in the test tube is a liquid soulution and is Transparent,and it was Metanol with Blue food dye added to it. when we where figuring out what the substance was we observed that the substance had no bublbles but it had a Manisucus.
date: March 3 -08
Chemical lab-
Coper Sulfate,Surcrose, and Sodium Chloride , all formed a soulution in are lab. when the substance disovled it ment it was transpaent, uniform if it didnt disolve.
When writting a conclusion always start out with creating a web. You should write down the main points and before writting alway 's think about what your going to write .

I learned that sucrose was soluble in water which means it was able to desolve.I also learned the difference between a solute and a solvent.solute is dissolved into a solution and solvent is dissolved to form a solution. A solution is a mixture that is a single substance but it is composed of a particle of two or more substances but are distruted evenly among each other. Dossolve is when the solute particles break apart and mix in with the solvent particles
Wrting a conclusion:
Always use PEN !
Never use the words You, We .
Plan what to write before writting it
use your data

Solution lab-
The purpose was to find out which chemicals form a solution with water. Independent variable- Type of chemical, coaper solfaite, zinc oxcide, sodium chloride. 6 trials each. Constants- Amount and color of the water. Procedure. 1. Place scoop of a tip of the chemical, in a test tube. 2. Measure 20 mL. of water using graduated cylinder and place it into the testube. 3. Shake test tube. 4. Put stopper on the test tube. 5. record observations. 6. Use a ruler and make the table nice and neat.
Vocabulary Words:
Uniform- Same throughout the liquid.
March 13,2008 Element- A pue substance that cannot be seperaated or broken down into simpler substances by physical or chemical means. THE SUBSTANCE IS?
When using internet resources we learned how to find the main idea and how to pick out the main parts of the topic.
Welcome! (:
